HAN D-G UARD FOR FRlEZER-MACHINES,

SPECIFICATION forming part of Letters Patent No. 498,263, dated May 30, 1893.

Application filed December 21, 1892. Serial No. 455.879. (N0 model.) I

To all whom it may concern: 7

Be it known that I, MICHAEL HENRY, a citi zen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Hand-Guards for Friezer- Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and numerals of reference marked thereon, which form a part of this specification.

My invention relates to improvements in hand guards for friezer machines, the features of which will be fully hereinafter described and claimed.

The object of my invention is to protect the hands of those operating a friezer against injury from the revolving cutter. I accompli'sh the object by the mechanism illustrated in the accompanying drawings, in which- Figure I is a front view of the device, showing a portion of the table of a friezer, and the suspended post to which the same is attached. Fig. '11 is a broken enlarged view of one leg of the device.

Like letters and numerals designate like parts in the two views.

The post A is attached to the ceiling and thoroughly braced directly over the friezing machine. The holding plate 13, provided with lugs to receive the shaft, is securely bolted to the end of said post. The shaft 0 is cylindrical, and is provided with a longitudinalgroove, and on the extreme end is a screw-thread which engages the T-joint L. The portion of said shaft adjacent to said screw fills the socket of said T-joint, the upper portion being held in theholding plate as indicated above. The pin .9, indicated by dotted lines, of the holding plate prevents the turning of said shaft, and when the parts are set in proper position, the said shaft is fixedly held by the hand screwl. The joint L has an orifice through its center, to receive the rod D, the same being held against a longitudinal movement by the hand-screw 5, which engages a threaded portion of said joint. For convenience of adjustment of the cm, is-

tached the guard G, and when properly adj usted is rigidly held by the hand-screw 6.

The entering stern may have an annular groove for the end of the screw to enter, so that in backing out said screw slightly, the guard will not drop. This guard is on the side from which the machine is fed, and

thereby protects the hands of the operator from being drawn against the cutter J.

The lines I represent the table.

The leg F is held on the rod the same as leg E, and when in position is bound by the hand-screw 3. To the'lower end of this legis pivoted the caster H. The construction and relationof the end of the leg and caster, are shown in Fig. II. The stem of the caster is provided with an annular groove, and into this face enters the screw 8,.which is bound by a lock-nut. The screw 7 enters from the opposite side and is likewise bound, and serves to arrest the downward movement of the plug 9, as the same is forced downward by the spiral spring 10. When the leg is pressed firmly against the board on the table of the frie zer, the caster is held yieldingly against the surface of said board. The effect is to hold the board steadily, and produce better results, than when the same vibrates because not thus held. The pressure on the board is somewhat regulated by pressing the shaft down, and then securing the same by the hand screw. The operation is simply to bring the caster down on the board to be friezed, and adjust the guard to a suitable position to protect the hands. The slightly rotative movement of the caster and guard, the vertical adjustment of the shaft and the lateral adjustment of the legs make the several adjustments easy.

Having fully described my invention, what I claim, and desire to secure Letters Pat- 1. The combination of the supporting-plate B provided with lugs, pin .9 and'the hand screw 1 for vertical adjustment, the grooved shaft 0, the joint L provided with the hand screws 4 and 5, the rod D, leg E,guard G pivoted to the same, leg F and caster H pivoted to said leg, substantially as set forth.

2. The combination of the shaft C, joint L, rod D, leg F, spiral spring 10, plug 9, arresting nut 7, caster H with annular groove in stem, screw 8, and guard G substantially as and for the purpose specified.

1o 3. The combination of the supporting-plate B, shaft'C, joint L, arm D, leg, E and pivotal guard G, substantially as described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

HUGH AEL HENRY.
